Question

Following are modern techniques used to protect endangered species EXCEPT _________

• A. tissue culture
• B. cryopreservation of gametes
• C. seed banks
• D. in vitro fertilization of eggs

Hint:

Look for the option that is a conventional method rather than an advanced technique for threatened species.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
Advanced ex situ techniques for threatened species include tissue culture propagation, cryopreservation of gametes and in vitro fertilisation of eggs.

Step 2: Key Point
Seed banks are a traditional ex situ storage method for seeds of crop strains, not an advanced technique built for endangered animal and plant species.

Step 3: Compare the options
So the option that is not among the modern techniques is seed banks.

Final Answer:
Seed banks are not among the listed modern techniques. \[ \boxed{\text{(C) }\text{seed banks}} \]
